Figure 3. Pairwise multilocus FST heatmap forTshr haplotypes. FST values were calculated
using the original method for estimation of genetic distance with
correction for sample size bias (Nei, 1978). Colors indicate pairwise
multilocus FST values ranging from 0 (yellow) to 1 (dark
blue). Western and Eastern European populations are ordered from long to
short predicted critical photoperiod (pCPP).
